       kgio 2.3.3 - minor fixes
       
       We no longer over-allocate memory for Kgio.poll (1.9.x-only).
       Under Ruby 1.9.3dev, we also use rb_thread_io_blocking_region
       to properly deal with cross-thread IO#close.

       poll: fix over-allocation for poll(2)
       
       Oops, fortunately we allocated too much and not too little.

       use rb_thread_blocking_io_region if possible
       
       It's in Ruby 1.9.3dev and tracks waiting FDs on blocked threads.

       kgio 2.3.2 - OpenBSD build fix
       
       Thanks to Jeremy Evans, this release fixes the build under OpenBSD.
   
   commit 8556c2ccf64840a080a928312d8feed2834d4d29

       Fix build on OpenBSD
       
       OpenBSD's getnameinfo(3) requires the sys/types.h header file, and
       including it should not cause a problem for other OSes.

       kgio 2.3.1 - compatibility fix
       
       * connect.c: disable AI_NUMERICSERV
       
         It's not needed since we already verify the service is a
         numeric port.  AI_NUMERICSERV is not available in older glibc
         (<2.3.4) and probably other old systems.

       kgio 2.3.0 - MSG_PEEK and poll(2) support
       
       recv() with MSG_PEEK for sockets is added with the try*
       interface.  SocketMethods#kgio_trypeek and
       SocketMethods#kgio_peek or Kgio.trypeek for non-Kgio-enabled
       sockets.
       
       For Ruby 1.9 only: poll(2) is exposed via the Kgio.poll
       singleton method and should provide an alternative for IO.select
       users.
       
       Both of these new features should work well on modern Unix-like
       operating systems.

       preliminary poll(2) support
       
       It's a nice alternative to IO.select for higher-numbered
       file descriptors, especially sparse ones.  Our interface
       also generates less garbage than IO.select does.

       add support for recv() with MSG_PEEK
       
       Kgio.trypeek, kgio_trypeek and kgio_peek methods are added
       for using with sockets.

       kgio 2.2.0 - kinder, gentler I/O for the Internets
       
       * sockets accept()ed by a TCP_NOPUSH/TCP_CORK listener
         automatically flush on kgio_*read calls if there is pending
         data.  "Kgio.autopush = false" disables this globally,
         and Kgio::Socket also get "kgio_autopush=" to enable/disable
         on a per-object individual basis.
       
       * ECONNRESET exceptions get empty backtraces for kgio_*read.
         There's nothing a programmer can do about these, so there's
         no point in going through the expensive backtrace generation
         process.
       
       * Kgio.try* singleton methods added for working with non-Kgio
         enhanced objects.  No more needing to use Object#extend
         and blowing away your method cache to make existing I/O
         objects kinder and gentler.
       
       * IPv6 support should be complete, systems without a native
         getaddrinfo(3) are now unsupported (and will remain so
         unless somebody complains).
       
       There should be no other backwards-incompatible changes other
       than requiring getaddrinfo(3) and friends for IPv6 support.

       add SocketMethods#kgio_addr!
       
       This refreshes (or sets) the @kgio_addr ivar for sockets
       that didn't go through kgio_accept or kgio_tryaccept.

       add proper IPv6 support
       
       No extra #ifdefs, we just won't support old systems without
       getaddrinfo() and friends anymore.  I doubt anybody still has
       them...

       avoid re-interning if GCC is not used (or under 1.8)
       
       Needless calls to rb_intern are wasteful in even semi-frequently
       used code.

       kgio_*read: empty backtrace for ECONNRESET
       
       There's nothing a programmer can do about ECONNRESET
       so just make the exception cheaper to raise so it
       can still be logged.

       autopush: enable accessors for client sockets
       
       Might as well allow clients to efficiently handle
       TCP_CORK/TCP_NOPUSH, too.

       autopush: enable this by default
       
       TCP_CORK (and presuably TCP_NOPUSH) aren't remotely useful in
       Rainbows! without this and there's almost no overhead for MRI,
       either.

       autopush: optimize away ivar usage under MRI
       
       We know that all versions of MRI have a small RFile structure
       that is allocated in the same object slots as other Ruby types
       and also zeroed on allocation.
       
       This optimization enables us to fall back to using ivars in
       case MRI changes or if we're used on other Rubies.

       rename nopush_smart to autopush
       
       This is probably a better name for it, libautocork is a nice
       name even though we won't use it directly.
   
   commit 910f6f3df099c04fcd55bd6b20785cce69cb36ae

   Date:   Thu Jan 27 19:43:39 2011 -0800
   
       preliminary implementation of "smart_nopush"
       
       It only supports TCP_CORK under Linux right now.
       
       We use a very basic strategy to use TCP_CORK semantics optimally
       in most TCP servers:  On corked sockets, we will uncork on recv()
       if there was a previous send().  Otherwise we do not fiddle
       with TCP_CORK at all.
       
       Under Linux, we can rely on TCP_CORK being inherited in an
       accept()-ed client socket so we can avoid syscalls for each
       accept()-ed client if we already know the accept() socket corks.
       
       This module does NOTHING for client TCP sockets, we only deal
       with accept()-ed sockets right now.

       kgio 2.1.1 - one small Rubinius fix
       
       We now avoid errno side-effects in kgio_wait_*able methods.
       This affects Rubinius, but may affect other Ruby platforms
       (particularly those that use stdio) as well.

       avoid errno side-effects in kgio_wait_*able
       
       Retrieving the file descriptor may have side-effects on
       certain Ruby implementations (e.g. Rubinius), so ensure
       our errno is preserved before calling rb_io_wait_*able().

       kgio 2.1.0 - accept improvements and fixes
       
       kgio_accept and kgio_tryaccept now take an optional argument
       to override the default Kgio::Socket class that is returned.
       
       These methods also fall back to using regular accept() if
       kgio was built on a system with accept4() and later run on
       a system without accept4().

       kgio 2.0.0 - major internal API changes
       
       (no code changes from 2.0.0pre1)
       
       This release should make Kgio easier and more consistent
       to use across a variety of libraries/applications.
       
       The global Kgio.wait_*able(=) accessor methods are gone in favor
       of having default kgio_wait_readable and kgio_wait_writable
       methods added to all Kgio-using classes.  Sub-classes may (and
       are encouraged to) redefine these if needed.
       
       Eric Wong (7):
           expand Kgio::*#kgio_read! documentation
           prefer symbolic names for waiting read/writability
           EOFError message matches Ruby's
           README: Gemcutter => RubyGems.org

       kgio 2.0.0pre1 - major internal API changes
       
       This release should make Kgio easier and more consistent
       to use across a variety of libraries/applications.
       
       The global Kgio.wait_*able(=) accessor methods are gone in favor
       of having default kgio_wait_readable and kgio_wait_writable
       methods added to all Kgio-using classes.  Sub-classes may (and
       are encouraged to) redefine these if needed.
       
       Eric Wong (7):
             expand Kgio::*#kgio_read! documentation
             prefer symbolic names for waiting read/writability

       methods.

       problems people were having with dalli 0.11.1+ while running
       Unicorn.

       kgio 1.3.1 - fix zero-length reads
       
       kgio_read and kgio_tryread will now return an empty string when
       a length of zero is specified instead of nil (which would signal
       an EOF).  This emulates the behavior of IO#read, IO#readpartial,
       IO#sysread, IO#read_nonblock in core Ruby for consistency.

       kgio 1.2.0 - cleanups and minor improvements
       
       The C extension is now split into several files for
       ease-of-maintenance.
       
       Slightly more common, client-triggerable exceptions (EOFError,
       Errno::EPIPE, Errno::ECONNRESET) are now less expensive as they
       are generated without backtraces.

       generate empty backtraces for EPIPE and ECONNRESET
       
       Malicious clients may disconnect during big writes to cause
       EPIPE and ECONNRESET exceptions.  Generating backtraces can be
       expensive with Ruby, so mitigate the DoS vector by lowering the
       cost of generating an exception.

       Make kgio_trywrite more aggressive with retrying
       
       Partial writes can be retried until completely denied with
       EAGAIN.  Often times, it is beneficial to retry immediately
       after a partial write because the kernel may allocate more
       buffers or the reader can drain the buffers.
       
       This helps the caller avoid crossing the Ruby <-> C boundary
       more than necessary.

       We'll stick with the "try" prefix if we're going to be

       where it's possible to release the GVL, allowing it to avoid
       thundering herd problems.  Otherwise it'll use thread-safe
       blocking under Ruby 1.8.

       split out reusable bits into separate headers
       
       No point in cluttering up the meat of our code.

       only use MSG_DONTWAIT under Linux
       
       MSG_DONTWAIT is less consistently implemented/supported on other
       platforms on stream sockets, so fallback to fcntl() + read()/write()
       for stream sockets.  This also fixes our previously broken support
       of non-MSG_DONTWAIT systems.

       beef up the test suite
       
       We need to test server <-> client interaction
       more thoroughly since some systems don't implement
       everything right.
